Multiband amplifier ma400
Product description
The multiband amplifier ma400 is intended to amplify RF signals in FM, VHFIII and UHF bands. The splitband design
ensures low intermodulation distortion.
Each input has 15 dB fine gain regulator and discrete 0/10 dB gain stage switch.
The amplifier pr12 V DC power for external equipment through each input connector
independently (control by
switches).
The amplifier can be used as stand-alone unit as well as modular system part powered from single power supply through
power input (5) or power distribution bus connector (6).
The amplifier is intended for indoor use only.
Safety instructions
Installation of the amplifier
must be done according
IEC60728-11 and
national safety standards.
The amplifier is powered from power supply unit (PSU) +12 V. This voltage is not dangerous to life.
Output of PSU +12 V must have a short circuit protection.
Any repairs must be done by a qualified personnel.
Do not plug the PSU +12 V into the mains socket until all modules cables have been connected correctly;
The mains socket of PSU +12 V must be easily accessible;
To disconnect the
amplifier completely, disconnect the PSU +12 V from the mains.
The amplifier shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall
be placed on it;
A
void placing amplifier next to central heating components and in areas of high humidity;
No naked flame sources, such as lighted candles, should be placed on amplifier;
If the amplifier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before
plugging into the mains;
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains;
Mount the amplifier in vertical position;
From top, front and bottom of installed amplifier
must be at least 10 cm free space.
